Without the SCR catalytic converter, the engine meets the Tier 2 emissions directive from the IMO, which calls for a 20% reduction in nitric oxide emissions starting in 2011. The third stage, IMO Tier 3, starts in 2016, and requires emissions to be reduced by 80%. Using the SCR method, the exhaust gas is treated with ammonia or urea and fed through a catalytic converter at a temperature of 300° to 400°C, further reducing emissions.

The company also introduced the VBS Mk 5 propeller generation, for a total of 20 hub sizes with diameters from 600 to 2150 mm, divided into three series designs: S, M and L. They handle power outputs from 1000 to 40 000 kW and reach an increases efficiency of up to 2%, said MAN.

MAN PrimeServ, the after sales brand of MAN Diesel & Turbo, also has created a feature that allows the chief engineer of any ship to switch from one type of liquid fuel to another automatically once a system has been installed.
